desert solar power to light up the world: The struggle Desertec







idea that promises to give light to the planet using a portion of desert as large as the Lombardy

Green energy and integration of electricity markets with the Maghreb. For the European Commission that is the winning strategy for the future of EU member states. It is also, needless to say, the most effective way to prevent tragedies such as the environment that has for more than two months, is affecting the Gulf of Mexico and putting at risk the credibility of U.S. President Barack Obama.

For European Energy Commissioner, Günther Oettinger, the desirable solution is called Desertec: the innovative idea, the whole of Germany, which would guarantee the provision of electricity to the citizens through the use of solar energy in the deserts of North Africa and the Middle East. A few days ago the plan was discussed in Algiers by the same Oettinger and Youcef Yousfi, Amina Afif Chelbi and Benkhadra, energy ministers of Algeria, Morocco and Tunisia. "I'm sure - has taken at the end of the summit Oettinger - that over the next five years will reach the European market for electricity production of the first facilities located in North Africa." Commissioner for the road is still long - we are talking about 20-40 years to complete the entire project - but even if feasible will require substantial capital to be able to go. The cardinal principle of

Desertec is based on the exploitation of sunlight in the desert areas that will be processed through the use of large facilities, with steam, in turn, activates a turbine that generates electricity as a central municipality. The issues raised by the consortium Desertec, project manager and consists of 12 companies, are really impressive: it would be enough to cover three collector arrays with thousands of a desert area, 40 million square miles, to meet global energy demand equivalent to 18 000 TW / h per year.

The target set in Algiers with a concrete plan of action signed by the heads of energy and, for now, much less ambitious and aims to supply over the next five years the area Eumenes (Europe, Middle East and North Africa) by facilitating a pilot project. The portion of electricity for the needs of the inhabitants of the Old Continent will, for the moment, only 15 percent. But the commitment of Brussels seems to be very serious because of the approaching time limit was set in 2020, the obligation for the EU to produce green sources by 20 percent of its total energy . Desertec, as claimed by Oettinger, could be conducive to this and other results, since, as argued by Gerhard Knies, the chairman of the supervisory board of the consortium, "In less than six hours deserts receive more energy from the sun than the 'humanity consumes in a year ". For the promoters of the platform, including the Italian Enel Green, who entered the consortium in March, the benefits would be more than one. With constant work aimed at creating a network connection submarine designed for the transportation of all forms of non-polluting energy, the network could Desertec, with an area of \u200b\u200blarge systems as Lombardy, giving sufficient access energy to 90 percent of the world population. No problem even for distances as the modern high-voltage lines that will be used will keep the level of energy losses below 3 percent for every 1000 km. And yet, they can activate new jobs in the Maghreb countries: a panel for the construction of a 250 MW unit will be deployed between one thousand workers and engineers for about 2-3 years. In addition, the enormous amount of energy, enough even to desalinate large quantities of sea water will be allocated to those countries that already now trudging to find available resources for drinking water. The studies already made that claim with a collector 250 MW and 200 MW turbine will be 100 000 cubic meters of purified water per day more than 4 million liter per hour.

Despite the advantages on paper there is already one who raises numerous objections. First on the "transaction costs", according to a first estimate, would amount to 450 billion euro: 20 needed to build transmission lines from 5 GW each. Enormity that, reassured by the consortium, could be reached immediately "with appropriate measures such as fixed rates had been developed in Spain and Germany. The need for these measures - they add to Monaco - would be reduced or disappear if we suppress state subsidies to fossil fuels or nuclear weapons and components are manufactured on a large scale. " Currently the rates would be prohibitive if you think that solar generated electricity would be charged a cost ranging between 125 and 130 euro per MW / hour compared with 48 € of the energy produced by coal power plants. Economic effort, however, may decrease with the standardization of the product which, when completely operational, will ensure a perfect balance of supply and demand and thus avoid waste. So what will ensure the availability of electricity during the night and periods of excessive cloud cover since the super-grid connection can be used for the transport of gas and biofuels. The process is already operational since 1985 in California where more than one company has used it in commercial use. The cut would also involve economic, Read BP case, the additional costs direct or indirect environmental damage and for the disposal of waste into the environment.

What's missing then? By the group repeated that the only element that prevents the start of the project is the lack of a strong political framework in some states that are potential producers of solar electricity. They do not seem enough predictions of the authors argue that "In the case of a voluntary interruption of supply from the producing countries will lose immediate revenue from energy sales, in contrast to what happens to the energy generated from fossil fuels that can store and sell later at higher price. This is compounded by the loss of confidence in the nations of the Middle East and North Africa from their customers and prospective donors. " The latter, both public and private, as very concerned the deal, do not put a penny unless it has previously received assurances on the safety of their investments.

ants

Someone says: Not only is the land of sly.
finally - perhaps - is starting to move something.



The battle of the ants.
Italy that is still his duty



Hello. I am the man who pays a tram ticket. The volunteer who assists the elderly themselves. The citizen who can not escape taxes. The lady who calls please. The pensioner who is in the corner offices. The manager who listens. The doctor who looks at his watch. The craftsman that coffin on the accounts. The student who does not believe in lotteries. I do not

sgom. Do not appear. Do not look for shortcuts. I do not give up. Sometimes work for others. I stop on the strips. Do not throw cigarette butts on the streets. Waiting for my turn to speak. Do not park on the sidewalk and even in the second row. I do my duty. Study, because it is important to win competitions. I'm going to vote and not by the sea. I send my children to public school. I do not think tronista or tissue. Sometimes I follow my passions ..

Letters from the Land of No, of Italy (citizens) forgotten who write to newspapers to have a hope and summarize the decline of a common life, affected by a terrible question: who makes you do? Young people who are frightened, "I fear for my future, the world, of all people, not I can see the rest of this story is telling us "(Martin, twenty years). Elderly people get depressed, "I am disheartened, disgusted. All steal, everyone eats, everyone makes endorse or recommend. If you're not so they cut off "(Barbara, seventy-five years). Girls who are questioning. As Giulia. Exemplary history that is not news, but indicates the retropensiero that hovers over us as we make a commitment: it was worth it?

Throughout the year, finished the lessons, twice a week, Julia becomes fifty kilometers to attend the most famous dance school in Italy. And after two hours at the bar and fifty miles back, is again home to do homework. It is good in class and dance. She has no time for Playstation, Xbox, not stun in front of the TV. The garden you see in the first patch of sun to practice in steps and in the wheels: on one hand, two hands, sideways. If he can continue to be allowed a daily basis: it will mean the school, then thirty miles, the lesson at the Scala, another fifty miles, the tasks and so on, except the days of the tests for all events, when it will be committed until the evening. For years and years, every year in the fear of change: risk of exclusion from school of dance.

Even now, some friends began to not understand. He wonders why there so hard, so stress, hard work. Julia wonders why he enjoys going back and forth giving a lot of fun stuff, when just appear in a TV broadcast or sway a bit 'to achieve the same goal: get out of the fray, to have a front row seat. You spend millions of Euros on TV to enhance pupae, facial tissues and even Velona. It is more or less unintentionally mocks those who have chosen a commitment, who does his work conscientiously. "They pay more sacrifice, study, hard work in this country?" Is the question that sends Julia into the well of the mail, looking for a non-obvious answer.

There was someone like her once in Milan. She was the daughter of a streetcar. With sacrifice and with the talent became Carla Fracci. But there is no more future than once, the writers today write on the walls. In the temporal paradox of graffiti semiologist Francesco Casetti law the need for non-trivial expectation. "It calls for the future, there is still no, not from this, but from the past that no longer exists. Yesterday there was a sense of tomorrow, today lacks this sense. And you must go to what is gone (the past) in order to recover what is not there yet (tomorrow). "

must rely on memory, then, because the opportunities are not geographical horizon of the various noises that no one of the boxes mail. Compared to yesterday, the web of intrigues polluted the air and narrow the boundaries of civic etiquette, as written by Sergio Romano. "The slope of our common life is affected by the misconduct, sometimes despicable, now standard practice," is the thesis of Maurizio Viroli, that the forfeiture of good practice has devoted a long discussion and a book called explicit (Freedom of servants, Einaudi).

"When you say that there is also a country for no one pulling the plane?" Calls for a doctor who in four decades ripped the final contract of employment. Women in medicine struggled to find a place, he writes: when they are good and competitive, not aligned to the standard of rampant or friend of the boss, the cut off immediately. If you have children are penalized. If you give it too much to do are scolded. If you do not line up, are marginalized. Bullying is common practice in the wards. Without sponsors, politicians in the hospitals is made difficult career ...

fondles a new deal is the civic, the discovery of new heroes. It calls for a start in politics. Massimiliano Panarari, professor of political science at the University of Modena (Italy gossip from Gramsci, Einaudi) prophesies the destruction of the dough deadly subculture that fuels the el'antipolitica. But not short, "The vision of the world in Italy is based sull'irrealtà too. " The psychiatrist and writer Vittorio Andreoli is even more skeptical: "I am afraid that this company does not ask anything, just ask and only technology where the technology void, change behaviors, it shows us what is needed to survive well, but does not solve the meaning of life. Gradually we are becoming the primary by technology in a society of injustice. "

Poor None, clinging to the hope of a normal country where good morning, as he said Zavattini, it means really good morning. Ants out of date in general flattening of the cost to society, which could be crushed between giant shoes stony and desolate, like Anna Maria Ortese imagined twenty years ago in a memorable story of Milan. A child, unfortunately slipped under the wheels of a tram, which offers lightning father anguished reflection on the meaning of life: "We are like ants, right, Dad?".

Should we say "Enough!", As the designer Giancarlo Iliprandi that the Politecnico di Milano theorizes a cultural movement to change between the air and makes a great anniversary as prime contractors Dorfles. "Just that we do not like / Just without dirtying the walls / Just to communicate the desire to change."

or call out, as Luca Goldoni, investigator of the long course of national conduct, that at some point we realized that no longer lived in the same country where he was born. "It happened when I read an intercepted phone call between a politician's friend and former classmate waiting for a TV audition. "There was no way to give me a contract," said one. And another: "And how did you get it?". "There was no way to convince him." "So what?". "So Did I date". "

No matter who you are but who you know, you philosophizes the student blog. Would a virus to the culture of convenience, "because if you do not rebuild a society based on mutual obligations we know not even enjoy our rights "Says Viroli. Need some act of courage in a country being blackmailed by selfishness and cracks. "No one begin to defend the few pebbles in the shoes of the great - said Don Antonio Mazzi, founder of Exodus - and do something about the lives of waste, even schools for the repeaters in this system just human, like Don Milani in Barbiana. Examples, responsibility, commitment, moral cleanliness, the only one parameter can not be legally recognized as that of money, they write so many. Then an indignant citizen drops a question. "Who came up with the wheeling and dealing, may have startled moral?". We, as the ants orthoses, we hope. But it is legitimate to doubt.
